AUTOMATIC GLOSING ATTACHMENT FOR VALVES.

`Application filed December 12, 1921.- 1 Serial No. 521,694.

To all whom it may concern. p

Beit known that I, Fran L. CnAMr'roN, a

citizen of the United States, and resident ot Kansas City, Jackson County, State of Mis. souri, have invented a certain new and-useful Improvement in Automatic Closin Attachments for Valves, of whichthe o lowin'is a complete specification. l his invention relates to automaticA clos ing attachments for valves, and more especially for valves controlling the supply of` liquid fuel to burners for furnacesl and the like, my primary object being the Vproduction of simple and etiicient means for catching Huid overiowing from the burner in the event of the accidental extinguishment of the Haine, and utilizing the Weight of such uid for closing the valve to cut off the fur ther supply of fluid .to the burner.

A further object is to provide means to applying auxiliary force, in the shape of a blow or impact, to insure the full and complete closure of the valve after the weight of the fluid has started the valve on its closing movement.

With these objects in View, the invention consists in certain novel and useful features 'of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which:

Figure 1 is a side elevation of a burner equipped with an attachment embodying the invention.

Figure 2 is an end view of the same.

Figure 3 is an enlarged vertical section valve 3 for regulating the degree of opera-- tion of the burner. It is also provided with a valve 4, the stem of which is formed with a'rectangular or squared outer portion 5 and a shoulder 6 at the inner end of said portion.

A rocking beam 7 is provided with a circular opening 8 fitting upon and rotatably adjustable on the rectangular or squared 4portion 5 of the stem, and said beam is prore 4 is a section taken on the line I vided at opposite sides with roughened or rosette faces 9 around the said opening 8.

A rosette collar 10 is nonfrotatably mounted on the stem at the inner side of said beam, and a rosette collar 11 is journaled or rotatably mounted on the stem at the outer side of said beam, the said rosette collars engaging the rosette faces or portions of the beam, and in order that said parts shall be clamped `firmly together and thus be incapable of movement independent of like movement by the valve, a washer 13 is fitted against the outer end of the valve stem and against the outer face of collar 11 to close the opening 12 thereof, and a lscrew bolt 14 extends through said washer and into said stem, the screwin home ot said bolt clamping the said co ars and the said beam firmly together.-

A receptacle 15 is suspended by a link 16 or in any other suitable manner from one end of said beam and tends to rock the same in the proper direction for edecting closing action of the valve, the parts being so proportioned however as shown most clearly by igure 2, that the valve normally stands open.

The rocking beam has up turned ends through which extend a rod 1 7, the end of said rod at what may be termed the heavy end of the 'beam, being provided with threads and carrying an adjustable poise or weight 18, the vadjustment of which'determines the delicacy of .operation of the valve. The said rod betweenthe up turned ends of the beam is smooth, and mounted slidingly thereon is a weight 19. v

When the valve is open the rod 17 is pitched downwardly at a suitable angle toward the heavy end of the beam so that the weight 19 shall slide to such end of the beam and `hence coopera-tein holding the valve open.

A. part of the attachment comprises a pan 20 arranged below the burner s0 that oil overflowing from the latter shall fall in said pan, and said pan is equipped with a drain tube 21? `for discharging the oil caught by the pan into the receptacle 15. rll`he pan and tube may be supported in any suitable manner and occupies a fixed relation with respect to the burner. p

With the -parts arranged as shown and described and assuming that the iiame at the burner becomes extinguished from any cause, it will be apparent that the oil will overflow from tli(` burner and fall into the pan and pass from the latter through said tube into the receptacle and eventually raise the weight of the latter to more than eounterbalance the heavy or weighted end of the beam. As a result, the receptadccarrying end of the beam will swing downward and begin closing movement of the valve. In this rocking action of the beam, its heavy end will rise to a higher plane than the receptacle carrying end and as a result, the weight 19 will slide upon the rod 17 and after it passes a certain point will cooperate with the receptacle in the valve closing movement, the impact of the sliding weight against the receptacle-carrying end of the beam tending to insure a .coniplete and full closure of the valve, the parts being so proportioned that when the valve is fully closed, the weights 18 and 19 occupy such positions that they cooperate with the weighted receptacle in holding the valve in such position. To reset the attachment, the liquid fuel in the receptacle is drawn or poured off and then the beam is reroc-ked to its initial position as shown by full lines in Figure 2, the weight 19 sliding to the left and thus cooperating with the weight 18 in holding the valve reliably open.

From the above description it will be apparent that I have produced an attachment embodying the features of advantage set forth as desirable in the st atement of the objects of the invention, and which may be obviously modified in minor partifulars without departing from the principle of construction and inode of operation` involved.

What I claim is:

1. The combination with a liquid fuel burner and a valve for controlling the flow of fuel to the burner, o f an automatic closing attachment for the valve, comprising a device movable rotatably as the valve is Closed or opened, and normally holding the valve in the last-named posit-ion, a receptacle exerting force tending to cause the device to rock and close the valve, an adjustable weight for cooperation in holding the valve normally in open position, a slidable weight for cooperating with the first-named weight in holding the valve open and for movement toward and impact against the said device at the receptacle carrying end thereof when the valve is closing, and means for discharging liquid into the receptacle to cause the same to over-balance the said device and weight and start closing movement of the valve.

2. The combination with a rotatable valve, v

of a beam rotatably adjustable on the stem of said valve, means for securing said beam in rigid relation to the valve, an adjustable weight movable with the beam and tending to hold the same with the valve in open position, a receptacle to be Weighted for rocking the beam and elosinvr the valve, and a weight slidable longitudinally of the beam and adapted when the valve is closed to cooperate with the first-named weight in holding the valve open and to slide toward the opposite end of the beam after the valve is started on its closing movement by the Weighting of the. receptacle, to strike said beam| and cooperate with said receptacle in insuring the complete closure of the valve.

3. The combination with a fuel supply pipe, of a valve controlling said pipe, a beam Secured to the valve and provided with. upturned ends,` a rod secured to the beam and extending from one of its arms through the other arm, a Weight manuallyadjustable on the rod, a weight slidable on the rod between the upturned endsv of the beam and a receptacle suspended from the beam at the opposite side ofthe valve from the adjustable weight, said receptacle when sufiiciently weighted imparting movement to the beam for closing the valve and thereby causing the slidable weight to slide upon said rod away from the adjustable weight and by striking the opposing upturned end of the beam, cooperate with the weighted receptacle in closing the valve.

In witness whereof I hereunto affix my signature.
